As a retired public health nurse, that worked for 32 years in communicable disease program,I can tell you vaccines work. In 1979 when I started many of the vaccines given today did not exist. The general public does not hear the pain in the parents voice when a child as died from a vaccine preventable disease. The general public, parents included,, need to heed the advice of the experts in the field. As new vaccines became available the incidence of that disease in the general population dropped. I will use the pneumococcal vaccine(prevnar) for children as an example. I can remember that we had 25 cases of invasive pneumococcal disease (found in blood) and reportable by law in ICUs in hospital the year before the Prevnar vaccine was given routinely to children. The next year that dropped to 5. I had children in my county die of HIB and chickenpox, two older adults experience the horror of tetanus, although the did survive, several children experience pertussis and according to the parents breathing issues for many years. Immunizations and disease prevention are very personal to me due to the years of experience that the general public and most parents are lucky enough to not have. I also gave thousands of free vaccines through the vaccines for children program to the under and uninsured population and can tell you that the government listens to reactions and changes the vaccine . For one example, the old DTP caused more fever and soreness for children and was changed to DTaP, The oral polio vaccine was changed to the injectable polio vaccine due to the possibility of vaccine related polio due to immunisupression. I followed the advice of the CDC and will continue to follow it with my own vaccines as I age.
